Answer:
0.45576
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Standard Deviation = √variance
Mean = 50
= √9
= 3
z = 51 - 50/3
= 0.11111
Probability value from Z-Table:
P(x<51) = 0.54424
P(x>51) = 1 - P(x<51)
= 1 - 0.54424
= 0.45576
The probability that the dealer will sell 51 or more cars is 0.45576
8x + 5y = 2 → 5y = - 8x + 2 → y = (-8/5)x + 2 ⇒ m = -8/5
perpendicular slope = 5/8
Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the given point
y - (-7) = (5/8)(x - 2)
y + 7 = (5/8)(x - 2)
8(y + 7) = 5(x - 2)
8y + 56 = 5x - 10
8y + 66 = 5x
66 = 5x - 8y ⇒ 5x - 8y = 66
Answer: 5x - 8y = 66
Answer:
option D.
Step-by-step explanation:
let's take any point on the graph. let's say (2, 16)
and one point we know is (0, 0)
= 16($) / 2 (hrs)
= 8 $/ hrs
that is option D.
Speed = distance / time
speed = 1(mile) / 4 (minutes)
speed = 0.25 miles per minute
s = 0.25m <== ur equation
there are 60 minutes in an hr....so sub in 60 for m
s = 0.25(60)
s = 15 miles per hr <====
Here are some examples:
1: has two parallel lines
2:it is also a rectangle
3: has 4 sides
4: can have sides that are equal
